Hey guys

I'm new to this and I need an RC set up controlling just servos. I'm running steam powered train models and they won't require an ESC, what I want to know is do receivers treat an ESC like a servo, and would a servo work in an ESC port?

All of the controls are actuated by small levers and valves in the cabs of the models.

What kind of RC transmitter and receiver would you recommend for this? I'd ideally like something that could potentially handle up to 4 servos, for power, direction, gas control, and a whistle valve. Ali Express seem to be having a really good sale at the moment, so I'd like to be able to take advantage of that if possible.

Changing the direction is handled by a short throw lever in the cab, and I'd like to be able to put this on a 3 way toggle switch ideally, or at least a channel that keeps the direction of throw for the duration of the run. I'm aware I'll have to do some programming of the whole thing, so something simple would be very helpful indeed.

Attached is a video of what these will be going into. Space is limited, however most of the controls don't require much force to operate at all. I do apologise for the stupid questions, but I'm quite keen to not fuck this up.

Cheers!
